Who We Are

Leadership Team


"Without doubt, the success of our health system to deliver high quality care at lower cost depends on a foundation of strong primary care services. The ongoing crisis in primary care demands imaginative solutions, and I am incredibly excited to participate in this important HMS initiative to revitalize primary care by redesigning the work of primary care doctors, and developing new educational models."

In his prior work at BIDMC, which included serving as Chief of the Division of General Medicine and Primary Care, he led a task force to improve transitions in care, a working group to develop new sustainable practice models for primary care, and a task force to develop strategies for care management for high-risk patients. At the state level, he served on the Massachusetts Coordinating Council on the PCMH. He has championed palliative care services in primary care, wellness programs and innovations to improve quality of life for patients with chronic illness.

A graduate of Massachusetts Institute of Technology and Stanford University School of Medicine, he has held leadership roles in the Society of General Internal Medicine, serving as Chairperson of the Research Committee in the past, and is past president of the Association of Chiefs and Leaders in General Internal Medicine. Currently, he is co-chairing an effort among the primary care societies to bring together the primary care disciplines to consider ways that primary care can contribute to improved population health.

With more than 200 publications, his research has spanned disparities in care, screening for infection in office practice, patient safety, end of life care, and interventions to improve care for patients with chronic disease. He has been recognized for his excellence in mentorship by the HMS Barger Award. He led the Harvard General Medicine Fellowship Program for nearly 15 years, and the Harvard Research Fellowship Program in Integrative Medical Therapies for 12 years. He held a Mid-Career Mentorship Award (K24) from the NIH to support his mentoring activities. He has mentored more than 50 trainees, most of whom have gone on to successful careers as investigators and leaders in general medicine.


"It's tremendously exciting to be involved at this watershed moment for primary care and for our healthcare system. The enormous energy and potential among our trainees for this work is palpable and gives me great hope for the future of medicine and healthcare."
